Improved barrel for holding petroleum



UNITED STATES PATENT OFFICE.

IMPROVED BARREL FOR HOLDING PETROLEUM.

Specification forming part of Letters Patent No. 50,694, dated October31, 1865.

To all whom it may concern Be it known that we, LESTER DAY and HENRYCHAPMAN, both of the city of Buffalo, in the county of Erie and State ofNew York, have invented a new and Improved Barrel for HoldingPetroleum-Oil and other like Penetrating Liquids; and we do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, makinga part of thisspecification, in which- Figure I is a vertical section of said improvedbarrel, showing also an improved bun g in connection therewith. Fig. IIis a plan of a key for opening the bung.

The nature of this invention relates to a barrel or cask the outer partof which is made of wood for strength and the inner part is made of thinsheet metal-such as tin, zinc, lead, iron, or other similar metals, (orcompounds)- for holding the liquid, the wood and metal forming acompound barrel or cask for holdin g'liquids.

In the order ot' construction, the inner metal barrel is first made.This is represented in the drawings atA, andis made of thin sheetmetalsuch as tin, lead, zinc, or the likeand is made in a barrel form ina common manner of working such metals. It is not made straightlengthwise, but is made in a bilge-barrel form, and so proportioned thatwhen the wood part is put around it there will be a slight space betweenthe wood and metal near the ends, as shown at J, Fig. 1I, Sheet I.

A ange or rim is formed at the joinder of the head K with the body Lofthe metal barrel, as shown at K', so that this flange may enter thecrozing of the outer wood barrel with the head and be firmly heldtherein, as shown at K2, Fig. II. This insures a substantial and trmconnection ofthe metal barrel to the wood barrel and prevents torsion,and at the same time a small space is left between the two, so that thehoops on the wood barrel may be driven on in case of any shrinkage ofthewood barrel.

By this construction a very strong barrel is made, peculiarly adapted'to its purpose 5 and the inner metal barrel, although firmly connectedwith the wood barrel, willnotinterfere with tightening the hoopsthereon.

The wood part Bis made ofstaves and heading in a common manner, andisset up around the formed metal, so that the metal will be completelyincased within the wood, the wood tting closely to the metal, exceptingthe space J, before described, forming a combination metal and woodbarrel, the metal being upon the inside for holding the liquids and thewood being upon the outside for strength and protection.

The outer wood barrel may be wholly made, rapidly7 and accurately, bymachinery, and a cheaper material may be used than would be required ifthe barrel was to be wholly of wood. Metallic hoops are used, as shownat C.

We have made an improved metallic bung which is particularly designedfor this kind of barrel, and may be used to advantage in common woodbarrels and casks. It consists of an outer thimble, D, which in lengthequals the thickness of the stave and metal, and has a flange or rimwhich laps onto the metal on the inside of the barrel when it is putinto place. It is inserted from the inside, and has vertical ribs whichenter the wood to keep it from turning when the stopper is screwed in.It is soldered to the metal, so as to make an air and water tightconnection. It has an internal screw for the reception of the stopper.

The stopper is represented at E. It has an external screw-thread on itsexternal surface corresponding to the internal screw in the thimble, andscrews tightly therein. It also has a depressed socket, as shown at e',for the reception of a key for turning it, and a flange, c2, which isembedded in the wood when it is put into place, so that it comes liushwith the surface ot' the barrel.

A packin g-rin g can be used, it' necessary, between the flange ofthestopper and the thimble.

We have placed a similar bung in the head ot' the barrel for the purposeof showing a slight modification, and in order to adapt it to thereception of a faucet for drawing liquid from the barrel when required.This is like the other, with the exception that it has a col- 1ar,f,which screws onto the thimble and laps onto the wood on the outside.

A faucet may be inserted in the thimble D when required, and when notrequired a stopper may be inserted, as in the other.

Grepresentsa key for screwing and unscrewl Wood barrel, for the purposesand substantially ing the stopper. as described.

'What We claim as our invention, and desire i to secure by LettersPatent, is-

A combined metal and wood barrel made in a. blge-barrel forni, the metalpart.' having Vitnesses: a an'ge or rim, K', formed thereon, which, GEO.W. VALLAGE, with the Wood head, enters the erozng of the B. H. MUEBLE.
